Going swimming this weekend? AHS has two Water Quality Advisories in place for our region

With temperatures in the mid-20s and no rain in the forecast this weekend, you might be thinking of heading outdoors – maybe, doing some swimming. 

Please keep in mind of a couple of Water Quality advisories for our region. 

The first – at Writing-on-Stone Provincial Park, is for elevated levels of bacteria by the beach in the nearby Milk River. 

Alberta Health Services warning of skin, ear and eye infections with water contact and gastro issues, like vomiting and diarrhea, if you happen to swallow the water.

The same holds true for the Milk River Reservoir, south of Raymond, where blue-green algae has formed near the shoreline. 

AHS is, again, is strongly discouraging any swimming and wading into the lake as the blooms have toxins that can make you or your pets very sick. 

Both advisories by will stay in place until further notice.
